Rachee Singh

I am an assistant professor of Computer Science at Cornell University. My research interests are in computer networking with a focus on server-scale, rack-scale and long-haul photonic interconnects. My group develops systems and algorithms for efficient communication using photonic interconnects. We apply these systems to improve the performance of important applications like distributed machine learning and general planet-scale cloud workloads.
